Problems solved by technology
[0004] This method has the following disadvantages: 1. Manual reading and manual recording of data is prone to errors in the data reading and recording process; 2. Manual reading of data, because the test delay time is controlled by the tester, there is no standard, resulting in test consistency Poor, and different testers may get different test data; 3. The test efficiency is low by manual reading and manual recording

The invention discloses an automatic testing method for parameters of a microwave oscillator. The automatic testing method comprises the following steps of powering up the to-be-tested microwave oscillator; transmitting a signal to a first coupler by the microwave oscillator, transmitting a main signal of the first coupler to a second coupler by the first coupler, transmitting a main signal of the second coupler to a power meter by the second coupler, transmitting a branch signal of the first coupler to one of a frequency spectrograph and a frequency meter by the first coupler, and transmitting a branch signal of the second coupler to the other one of the frequency spectrograph and the frequency meter by the second coupler; controlling the power meter, the frequency spectrograph and the frequency meter by a control device to test the microwave oscillator, acquiring testing results and storing, and controlling a display device to display. According to the method, automatic testing of the working frequency, the output power and the phase noise of the microwave oscillator can be realized, and data does not need to be manually read and manually recorded, and therefore, the accuracy and the consistency of the testing results are improved, and the testing efficiency is improved. The invention also discloses an automatic testing device for the parameters of the microwave oscillator.
Description
Technical field [0001] The invention relates to a microwave oscillator parameter testing technology, in particular to a method and device for automatically testing parameters of a microwave oscillator. Background technique [0002] Microwave frequency sources are the key to achieving high-performance indicators for electronic systems such as radar, communications, and electronic countermeasures. The realization of many modern microwave electronic equipment and system functions directly depends on the performance of the microwave frequency source used, and microwave oscillators are used as microwave frequency sources. The core component is therefore very important. Microwave oscillators are used to generate microwave signals. It is the basic microwave energy source for all microwave systems such as radar, communications, navigation or electronic warfare systems. Its quality directly affects the performance indicators of these systems and is one of the key components of various mic...
